Best HDD brand?

There's been a lot of mergers and acquisitions in the hard drive world in case you haven't noticed. Western Digital bought HGST (Hitachi) and Seagate acquired Samsung's mechanical HD division so it's really only down to those two. The Toshiba drives that you see on most websites are really rebranded Seagate models. So it's kind of one of those "pick your poison" type of deals. I just got a Caviar Blue and it's been a great drive so far - well worth the $55 I paid for it.
